Section 8 EXDMA Controller
8.4.10
Single Address Mode (Read): Figure 8.22 shows an example of transfer when ETEND output is
enabled, and byte-size, single address mode transfer (read) is performed from external 8-bit, 2-
state access space to an external device.
Figure 8.23 shows an example of transfer when ETEND output is enabled, and word-size, single
address mode transfer (read) is performed from external 8-bit, 2-state access space to an external
device.
After one byte or word has been transferred in response to one transfer request, the bus is released.
While the bus is released, one or more CPU, DMAC, or DTC bus cycles are initiated.
